Question

Your large marijuana greenhouse facility requires 600 KW of power on an average day to maintain proper lighting and temperature to maximize crop yield. The greenhouse is in Denver and is at an altitude of 5000 ft above sea level. Determine the number of 25 m diameter windmills required to power your facility, which has a battery backup system for days where the wind velocity is less than average. Average air temperature is 41°F and the average wind velocity is 10 m/sec. Assume the windmills are 60% efficient and can extract energy with an exit wind velocity of 2 m/s.
